The SNAP-OMR6T-C mechanical power relay output module offers four channels of switching for up to 250 VAC or 30 VDC, 6 amp loads. Each of the four mechanical contacts can be used as normally open or normally closed. This module includes integrated transient suppression while maintaining minimal leakage current.
Mechanical power relay output modules handle more current than any other SNAP output module and provide channel-to-channel isolation. Fusing is not provided; you must provide fusing when wiring the module.
Each contact on the SNAP-OMR6T-C can carry 6 amps. Having more than one channel on at the same time does not reduce the amount of power each channel can carry. Because channels are not polarity sensitive, each channel can switch either AC or DC power, thus potentially reducing the number of modules needed.
In solid-state SNAP AC output modules, possible leakage current might cause a load to stick ON. In contrast, these modules dramatically reduce that possibility. Leakage current for the SNAP-OMR6T-C is less than 1 microamp.
Part of the SNAP PAC System, the SNAP-OMR6T-C mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley PLC system.
The SNAP-OMR6T-C is compatible with all SNAP PAC brains and rack-mounted controllers, including both standard wired models and Wired+Wireless™ models. It is also compatible with SNAP Ultimate, SNAP Ethernet, and SNAP Simple brains, as well as other SNAP brains such as the serial B3000 and the B3000-B. It can be used on both B-series and M-series mounting racks.
A similar module without transient suppression is available: the SNAP-OMR6-C. However, the SNAP-OMR6T-C is recommended for most applications, including applications with long wire runs.
NOTE: The SNAP-OMR6T-C is a drop-in replacement for the older SNAP-OMR6-A, which is obsolete.
NOTE: For very high inductive loads, additional transient protection is recommended.
